I am assuming there is an Access Point (AP) and IoT Nodes in NOMA uplink scenario. Following is assumed:
- the AP does not know the channel gain of IoT Nodes
the transmission power of nodes is also unknown to AP
How can we measure the SINR of the nodes: as we do not have the Power x Gain product without the knowledge of Power and Gain of IoT nodes.
Is it right to assume that the receiver of the AP won't be able to get any legible data (information) unless the SINR is above a certain threshold?
